You're not describing capitalism, you're describing managerialism with a manager-evaluation function of profit.

Managers do not need to be evaluated by EPS, but when you are a public company with diffuse shareholders (who are the actual "capitalists", and who include any of use with a 401k or pension), that's an easy one for people to agree on. Also, when your society gives up on the restraints of (in our case) Judeao-Christian values and say "we're just overgrown apes", well, then you get HBS style of management, because there's nothing restraining acting "because we can". I think we have a spiritual crisis more than an economic system crisis.
